Farmington, N. Mex. Filed Jan. 29, 196i), Ser- No. 5,456 Claims. (Cl.24-20514) This invention relates to the art of fastening devices and,more specifically, the instant invention pertains to the general fieldof slide fas'tening'device's. I

It is common knowledge that the conventional slider for slide fasteningdevices is so constructed that the outer face thereof is provided withears, tabs, or other similar bearing projections which extend outwardlyfrom the aforementioned face and between which is supported for pivotalmovement a manually manipulative pull tongue.

The heretofore known prior art sliders are possessed of a number ofdistinct disadvantages among which is the fact that the projecting earstaken together with the overlying pull tongue increase, undesirably, theoverall thickness of the slider, per se, causing an outward bulge of thematerial overlying the slider. Aside and apart from unsightly occurrencecaused by the bulgedout fabric overlying the slider, the conventionalslide fastening devices are also subject to criticism in that thethickness of such devices interferes, materially, with the pressing ofthe garment or article upon-which the slide tongue will not projectbeyond the plane of the outer Wall of the slider body.

A further primary object of this invention is to provide a slidefastening device incorporating in the pulltongue thereof unique meansfor locking the slider device against movement relative to the stringerelements when the pull tongue is moved to its locking-position.

Another object of this invention is to provide, in the slider for aslide fastening device, a pull tongue which -is pivotally connected tothe slider body adjacent one end thereof and, more particularly, whenthe slide fastening device is incorporated in mens and womens clothing,the pull tongue will be pivotally connected to the slider body adjacentthe upper end thereof.

A still'further object of this invention is to provide a slide for a.slide fastening device which is subject to inexpensive mass production,non-complex in construction and assembly and which is durable-in use.

Other and further objects and advantages of the instant invention willbecome more manifest from a consideration of the followingspecification'when read; in conjunction with the annexed drawing inwhich:

Referring now morespeeifically to the drawings,r'ef-- erence numeral 10designates, in general, a slide fastener constructed in accordance withthe teachings of this invention. The slide fastener includes'a pair ofstringer tapes 12 having confronting edges, and to the outerlongitudinally extending marginal edges of which are con;- nected theusual reassessment or teeth 14 The elemerits 14 are mounted on thetapes- 12 with the elements extending in alternating relation partiallyacross the space intervening-between the confronting edge portions. Theedge pontions'her e designated atio, carrying the fastener elements 14-,are extended within the outwardly opening sides of the slider, in theusual nianne'r. v

The slider 18-, to which the instant invention is addressed, comprisesouter and inner walls 20, 22, respectively, disposed in parallel planes(see FIGURE 2). The outer and inner walls Zil, 22, respectively, at oneend portion of the slider 18, shownasthe lower end portion in FIGURES 1to 5, inclusive, are formed with parallel side edges, with the wallsremaining of constantwidtli for a part of the length of the slider body,the walls 20, 22 thereafter progressively'increasing in width inadirection toward the opposite end of the body which constitutes theupper endof the slider as illustrated in the several figures of thedrawing. v

This,jof course, is a generally conventional configuration' of' a sliderbody, it being understood that the tapes are interlocked where theyextend out of the narrower end of the body, and are unlocked, indiverging relation, when they extend out of the wider end of thebody.

At opposite sides of the body or slide fastener 10, there are providedoutwardly facing guide channels 24 for the respective edge portions 16,the channels opening on opposite sidesvof the body andalso'openingthroughout their length upon the adjacent sides of the body.The {walls 20, 22 define side walls for the channels. In ner walls orwebs for the channels are defined byja ti-shaped guide structureprovided in the wider end of the body between the walls 29,22, saidstructure comprising divergent walls 23, which walls converge, a'tj'alocation medially between opposite ends of the body,

and diverge from this location toward the wider ,endgo'f thebody as isshown to particular advantage in- FIGURE 1. The walls 23 extend inlaterally inwardly-spaced relation relative to the divergent portions ofthe sides of the body, so as to cause the channels 24 to diverge toimpart a corresponding divergence to the stringer tapes where theyextend out of the wider end of theslider body. The channels 24, betweenthe point 'of. convergence of the walls 23-and the narrower extremity ofthe body, are in full communication with each other, sinceit 'is in thisportion of the length of the body that the fastener elements 14 of therespective edge portions 16 are interlocked (see FIGURE 1).

An endwall 26, at the wider end of the body, te'rrninates at itsopposite ends at the divergent extremitierof the wallsZtl, 22. 1

At the wider end of the body, the channels 24 are of where they openupon the sides of the body, through the provision of confrontinglongitudinal flangesformed upon opposite" sides of the side walls 20,22; These flangesare designated at-28, 30', respectively.

Intermediate the length of the body, the wall 20 is terminates adjacentthe top wall 26'.

The side wall 20 is also stamped or otherwise formed with a transverselyextending opening 34 (see FIGURE *2) across which extends a support rod36.

fhpeassv Reference numeral 38 denotes a substantially rectangular pulltongue having a hinge barrel 40 at its upper end integrally formedtherewith. As is seen in FIG- URES 2 and 5, the hinge barrel 40 isrotatably mounted upon the support rod 36.

The pull tongue 38 extends downwardly from the sup port rod 36 for adistance below the lower ends of the side walls 20, 22, and spacedinwardly from the lower end of the pull tongue 38 and adjacent the lowerend of the side wall 20, is a transversely extending substantiallyrectangular slide fastener lock member 42. Referring now to FIGURES l to3, inclusive, the lock element 42 is recessed at 44 at one end thereofproviding a depending shoulder 46 at its other end.

In operation, and assuming that stringer tapes .12 are engaged withinthe slider 18 in the conventional manner,

'as illustrated in FIGURES l and 2, and assuming further that it is nowdesired to lock the slider at a given point thereon, the operator movesthe pull tongue 38 from its open position shown in FIGURE 5 to itsclosed position shown in FIGURE 4, thereby causing the lock member 42 toextend across the fastener elements 14.

'In this construction, one of the fastener elements 14 will ;beoverlapped by the cutout portion 44 of the lock member 42, and theshoulder 46 will enter between a pair of fastener elements on the otherof the tapes to securely hold the tapes against relative movement withrespect to each other. I

It should be noted at this point that the pull tongue 38,'when in itsinoperative position, is substantially flush with the side wall 20, thatis, the outer plane of the pull tongue 38 is substantially coincidentwith the outer plane of the side wall 20.

Reference is now made to FIGURE 6 of the drawing 'in which a secondembodiment of this'invention is illustrated. To avoid repetition,elements of this second em- "bodiment of the invention findingcounterparts in the first embodiment have been assigned identicalreference numerals to which a prime mark has been added to clearlydifferentiate between the two inventions.

the structure and function of the slide 18 is identical to the slide 18described above.

It should now be self evident that a slider 18, 18' for a slide fastenerconstructed in the manner described above, eliminates all unsightlybulges in fabric material lying thereabove and, at the same time,materially decreases wear on the garment or other article to which theslide fastener is-attached.

Having described and illustrated one embodiment of this invention indetail, it will be understood that the same is offered merely by way ofexample and that this invention is to be limited only by the scope ofthe ap pended claims. 7
